Energy carrier allocation strategy for a hybrid wind farm with offshore electrolysis: A techno-economic optimization study from a developer's perspective

Hydrogen is emerging as a promising energy carrier that can potentially solve the challenges like long-term storage and intermittent power supply associated with a 100%-renewable economy. Moreover, hydrogen can be used in industry sectors such as steel manufacturing and aviation, which struggle with carbon abatement. To increase the supply of...

Integrating end-of-life wind turbine blades into a variety of building layers through multiple use cycles – a strategy to maximize the lifetime of wasted materials; a case study in Eemshaven

An increasing massive volume of wind turbine blades are coming to end-of-life in the Netherlands. These components contain mostly fibre-reinforced plastics, which has been banned from landfill and incineration. Since then, companies and institutions have spent their efforts to expand the lifetime of this material by developing a circular wind...

Site-specific validation of turbulence models on large offshore wind farms for improving fatigue assessment

Wind turbines installed in a wind farm are typically subject to increased turbulence because they are in the wake of upstream wind turbines that generate additional turbulence. Accurate prediction of turbulence in wind farms is critical as it is proportional to wind turbine fatigue loads, power losses and prediction of wind farm lifetime. IEC...

Offshore Wind Farm Optimisation: A Comparison of Performance between Regular and Irregular Wind Turbine Layouts

Wind farm layouts in industry show a range of patterns with an overall trend from regular to irregular patterns over time. Wind farm layout optimisation studies in literature generally result in irregular wind turbine patterns. Review of existing literature shows that the performance of irregular and regular wind farm layouts has not been...

Control of an offshore Bipole with AC interlink under dedicated metallic return fault to improve availability

The power system in Northern Europe supports a high degree of penetration of Wind Energy-based HVDC connections. Most of the modern HVDC connections will have Bipole with a dedicated metallic return (DMR) configuration. This thesis presents a basic guideline to increase the Levelized cost of operation of Bipole HVDC links by attaching the...

Machine Learning of Wind Plant Turbulence Anisotropy Fields

In studies of wind plant designs, wake dynamics are of great interests as wakes affect downstream turbine loading that impacts wind plant efficiency. Recent developments of Tensor Basis Decision Tree (TBDT) based machine learning (ML) models in reconstructing the turbulence anisotropy fields of simple flow cases prompt the motivation in applying...

Direct Trade PPA: Economic & Financial Benefits of a Direct Energy Contract With a Wind farm

In the Netherlands more wind farms are constructed and energy is contracted in long-term Power Purchase Agreemenats (PPA) to guarantee a steady revenue stream for the wind farm owners. However, until now only large corporates closed PPA contracts to obtain the Renewable Energy Credits (RECs) from a wind farm and claim to be renewable. A new type...

Integrated Control System for Frequency and Voltage Support via Type-3 Wind Turbines equipped with Energy Storage System

During previous centuries, humanity had relied on fossil fuels to generate the demanded energy. Nowadays, the extensive use of oil, gas and coal for energy production is becoming a major problem which concerns modern society. Global warming and climate change are the biggest challenges the scientific community has faced. The main factor which...

The Hybrid Power Plant: Optimal design and operation of battery energy storage as an addition to onshore wind farms in the Netherlands

In the Netherlands, wind power has the highest potential for future development compared to alternatives such as solar PV and biomass. The intermittent nature of the wind power resource calls for novel approaches to supply and demand management, as well as power quality assurance. Energy storage technologies allow for the separation between...

Distance Protection Challenges in a Wind Farm

Wind farms are currently built in the North Sea in the Netherlands. The grid connecting the off-shore wind farm to the main-land distribution grid must be protected against short-circuits and other electrical disturbances. In this project is studied if electrical protection of a grid is suitable for grids connecting renewable energy sources to...

Wind Turbine Contribution to Ancillary Services under Increased Renewable Penetration levels

Wind constitutes a dominant form of sustainable energy that is expected to grow rapidly in the years to come. Increased inverter-based wind power penetration may however endanger grid stability and reliability, if not enriched with the capability to provide crucial ancillary services to the grid, such as frequency regulation. In order for the...
